Walk more as a means to get around, not just for exercise. Wear normal street clothes and walk to a nearby store, walk to an eatery for lunch or whatever you can reasonably manage.

I gave up my car some years ago. The internet advised me that I did not live in a walkable neighborhood, even though I lived about as close to my job as was possible and there were three or four shopping centers within a 20 minute walk of my apartment. I began walking to work and I and my sons began walking to get groceries and do other shopping.

The entire neighborhood began walking more. The cops stopped staking out my apartment complex. The vegetation in the area got visibly healthier.

Walk more and set the example. I have seen this make a real difference in multiple neighborhoods.
